SPECIFICATION forming part of Letters Patent No. 589,271, dated August 31, 1897.

Application filed April Z6, 1897. Serial No. 633,893. (No model.)

To @ZZ whom it may concern:

Be it known that I, JOHN PLAYER, a citizen of the United States, residing at Topeka., in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Car-Trucks, of which the following is a spec-iiication.

The object of my invention is to provide a simple, economical, and efficient car-truck; and the invention consists in the features, combinations, and details of construct-ion hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of a car-truck constructed in accordance with my improvements; Fig. 2, an end elevation, partly in section, taken on line 2 2 of Fig. l, looking in the direction of the arrow; Fig. 3, a plan view of the main portion of a truck, partly in section, taken on line 3 of Fig. 4, Fig. 4, a side elevation ofthe same; Fig. 5, an end view of a truck-frame; and Figs. 6 and 7 transverse sectional elevations taken on lines 6 and 7, respectively, of Fig. 3.

In the art to which this invention relates itis well known that the usual car-truck consists of a combination of several different elements joined together,`comprising channelbeams, spring-seats, spring-hangers, center plates, truck-heads, arch-bars, side bearings, and bolster and bottom plates joined together by rivets, bolts,0r nuts,the expense of which is considerable, in that it requires considerable time to assemble the parts, as well as financial outlay for labor. It is also objectionable in that when repairs are necessary it takes considerable time to assemble the parts, which delays the car and prevents its being used for commercial purposes. The principal object of my invention, therefore, is to dispense with several of these parts and provide a cartruck the transom of which is formed in one integral portion which can be used whenever desired anddoes not require any assembling whatever, but merely the placing in position and tying together with the usual arch and tie bars, a description of which will be hereinat'ter given.

In constructing a truck in accordance with my improvements I make a transom consisting of two vertical side bars A, joined together at their lower end portions by means the lower side thereof, which has a perfora` tion d, through which the usual king-bolt may be passed whenever it is desirable or necessary.' In order to strengthen the part, it is provided with ribs or flanges Ct,eXtending outwardly at the upper and lower sides, which add rigidity to the structure as well as permitting a minimum amount of metal in order to resist the maximum strains.

j By an inspection of Figs. 3, a, and 6 it will be seen that the transom is open on the upper portion to form a pocket in which a bolster, as hereinafter described, may be inserted.

In Figs. 1 and 2 a bolster E is shown as iuserted in the pocket of the transom, between which and the spring-plates B cushion-springs G are inserted for the purpose of sustaining the load of the carin a yielding manner upon the car-truck. This bolster is made in the shape shown in Figs. land 2, preferably in an integral casting having a center plate e and side bearings e secured thereto, though they may be formed integral therewith, if desired. l The truck is secured to the car-axles, as desired, by means of the arch-bars 1 and 2 and tie-bar 3. Y.

It will be observed from an inspection of the drawings and the foregoing description that several of the old parts have been dispensed with-viz., the old braces and` four hangers that support the spring-seats and act to stiften the parts. The weight of the old structures is in the neighborhood of six hundred and ninety pounds, while a truck constructed in accordance with my improvements weighs between three hundred and five hundred pounds. The advantages are that the transom can be made in one integral portion, thus dispensing with several parts, and is always ready to use at a moments notice. Further, it is economical to build in that it is formed of cast-steel and requires no labor in assembling, other than IOO is required to bolt it to the Car-axle boxes, its upper :1nd lower portion, :L central per- 1o :md such parts may be kept in stock at dif formed cross-piece connecting the lower p0rferent points for the purpose of repairing tions ofthe side bars,a11d side strengtheningbroken-down trucks or making new ones. ribs all formed in one integral casting, sub- I olamstantially as described.
